Fire Sprinkler working principle diagram

Fire system works A fire alarm system 1, the system components (1) detector: smoke detectors, temperature detectors, flame detectors (2) manual alarm device: manual alarm button (3) alarm controller: Regional alarm, central alarm, control center alarm 2, the main function of the system to complete When a fire occurs, the detector will send a fire signal to the alarm controller, through the acousto-optic signal is displayed, and in the control panel to display the site of the fire, so as to achieve The purpose of forecast fire. At the same time, you can also manually alarm by manual alarm function. 3, the system prone to problems, causes, treatment methods (1) detector false alarm, detector fault alarm reason: the detector sensitivity of choice is not reasonable, the environment is too humid, the wind speed is too large, too much dust, mechanical vibration , The detector used for a long time, the device parameters decline. Solution: According to the installation environment, select the appropriate sensitivity of the detector, the installation should avoid the tuyere and wind speed larger channels, regular inspection, cleaning and replacement of the detector according to the situation. (2) Manual alarm button alarm, manual alarm button fault alarm Cause: The button is used for too long, the parameters drop or button man-made damage. Approach: Regular inspection, damaged timely replacement, so as not to affect the system operation. (3) alarm controller failure causes: the device itself is damaged mechanical failure or external detector, press the button manually alarm problems caused by the alarm controller, reported fire. Approach: Use the table or self-diagnostic program to check the machine itself, troubleshooting, or (1) (2) approach to check whether the fault caused by the outside world. (4) Line fault: Cause: Insulation damage, loose joints, environmental humidity is too large, resulting in decreased insulation. Approach: Check the degree of insulation with the table, check the connector, the connection using welding, plastic sealing and other processes. Fire Sprinkler Schematic II, the fire hydrant system 1, the system components Fire pump, pump (regulator tank), fire hydrant box, fire hydrant valve, interface water gun, hose, hydrant alarm button, fire hydrant system control cabinet. 2, the main function of the system to complete Hydrant system piping filled with pressure water, such as the system has a trace leakage, you can rely on the regulator pump or surge tank to maintain system water and pressure. When the fire, first open the fire hydrant box, according to the requirements to take the interface, water, the gun at the fire, open the fire hydrant valve, the water gun immediately water spray, press the fire hydrant button, start the fire pump through the fire hydrant to the pipeline Water supply. 3, the system prone problems, causes, treatment (1) open the fire hydrant valve waterless reasons: There may be leaks in the pipeline, the pipeline is dry, and the pressure gauge damage, the regulator system does not work. Approach: Check leaks, pressure gauges, repair or put on the regulator, the pipeline water. (2) press the manual button, can not start the fire pump linkage reasons: Manual button wiring loose, the button itself is damaged, linkage control cabinet itself fault, fire pump start cabinet fault or loose wiring, fire pump itself fault. Approach: Check the wiring of the equipment, the device itself, check the pump itself, the electrical part of the organization with or without failure and exclusion.
